METAL IPOLISH.

Application filed December 28, 1921.

To all whom it may concern:

Be it known that 1, WILLIAM a citizen of the United States,

Asbury Park, in

and State of New the county of A. R DDELL, residing at Monmouth Jersey,have invented specification.

This invention compositions and has as its object to relates to metalpolishing provide a composition especially useful in polishingsilverware, per, brass, ters, typewnters,

vide a polishing tinw are, aluminum,

GOP-

and other metals in cash regisautomobile parts, etc. Another object ofthe invention is to composition which prowill clean, polish, and platethe surface to which it is applied and wh employed to obtain a highpolish without the expenditure of great energy.

Another obj vide a polishing composi indefinitely.

The compositio n embod ich composition may be smooth finish and a ect ofthe invention is to protion which will not keep ying the inventionconsists of a mixture of silver cyanide,

otassium nitrate,

potassium cyanide,

white borax, whiting and alcohol. The

portions in which these ingredients present in ordinarily theingredlents in whiting 2 lbs, sa

distilled water about 2 qts,

course, vary with climatic conditions, more alcohol being employed wherethe composition is to be used in cold weather, or in a cold climate.

1n preparing the polishing compositions I preferably proceed as follows:In a portion of the water I dissolve approximately eight ounces ofpotassium cyanide and in the remainder of the water I dissolveapproximately one ounce of silver nitrate. These two solutions are thenmixed and in accordance with the chemical reaction which takes place thesilver content is converted into silver potassium cyanide, so that theresulting mixture is a solution of silvercyanide and potassium nitrate.To this mixture the whiting and alcohol, salt, and borax are then addedand the whole is thoroughly stirred for about fifteen minutes. Thecomposition is then ready for use and after a small quantity thereof hasbeen poured upon the surface to be polished the surface is wiped orrubbed with a soft cloth preferably dipped in warm water, after whichthe surface is polished with a dry soft cloth.

Instead of employing potassium cyanide, I may, of course, make use ofsodium cyanide.

Having thus described the invention, what I claim as new is:

A polishing composition comprising a mixture of silver-potassiumcyanide, potassium cyanide, potassium nitrate, borax, whiting, water andalcohol, in the proportions resulting from the ingredients named in thequantities herein specified.

In testimony whereof I aflix my signature.

WILLIAM ALBERT RUDDELL. [14.8.]
